CHART FOR VEHICLES.

To all wlw/nz. 'it may conce/m Be it known that I, Geenen E. BOYDEN, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York. have invented a new and use ful Improvement in Charts for Vehicles, of which the following is a description,

This invention relates to apparatus for producing and tracing road-charts, and has particular reference to means to be applied to moving vehicles, such, for example, as motor-cars, for the purpose of producing charts o-f roads over which the car is traveling, and for enabling the driver of the car to follow accurately any road delineated on a given chart.

Among the objects of my invention may beV noted the following: to provide a device, applicable to road vehicles, by which the driver of the vehicle may readily Vfollow the roads charted upon a web or map; to provide an apparatus, applicable to road vehicles, by which a. road over which the vehicle is traveling may be charted or produced upon the web in all its details of windings, ycurves and turns; to provide means, in combination with the steeringgearof a road vehicle, by which the driver of the vehicle may readily find his Way, or by which the way or road followed by him may be accurately charted for subsequent use; to provide a compact and simple means by which a road-chart may be caused to travel .under the eyes of the driver of a vehicle to which latter the chart may be operatively attached; and toprovide certain details of construction by means of which the foregoing objects are attained simply., cheaply and accurately.-

1With the above objects in View, and others which will be detailed duringtheV course of this description, my invention consists inthe parts, features, elements and combinations of elements, all as hereinafter described and claimed. l v

lfn order that my invention may be clearly understood, I have provided L drawings, wherein: v

Serial No. 661365,.

sis'of the motor-vehicule andthe front truck thereof showing the application of my invention thereto; Fig. 3 is a longitudinal, Y

central section of the chart-box or frame in which the charting mechanism is contained; Fig. 4 is a horizontal section of the chart-box taken just below the top thereof; Fig. 5 is a. vertical, longitudinal section of the chart-box taken just outside the sup-` ports at one side of the box; Fig. 6 is a sectional elevation showing a detail illustrating the means by which the charting or tracing mechanism may be thrown into and out of operation, the parts being shown in operative position; Fig. 7 is a View similar to Fig. 6 showing the parts in an inoperative position; Fig. 8 is a detail showing in sectional elevation one of the steering-wheels with the gearing connected thereto by which the exible shaft, connecting with the webfeeding mechanism, is operated, the section being on the line 8 -8 of Fig. 2; lEig. 9 is a sectional view showing a detail of the means by which the web-cylinders are supported; Fig. l0 is a sectionalvie'w showing the said cylinder-supporting means in another positi'on; Fig. l1 is a top-plan of another form of means for connecting 'the tracing-arm or stylus with the steering means; and Fig. l2 is a View similar to Fig. 2, but showing another means for connc-cting the steering mechanism with the tracing-arm or stylus.

Referring to the drawings, the numeral l indicates, in a conventional manner, an automobile to which my invention has been applied, 2 being the chassis, 3 the steeringwheel, the shaft el. of which extends and is journaled in usual manner. rlhe usual mechanism Connects the shaft 4 with the front wheels of the car, including the connecting-rod 5, steering-crank 6, the rod 7 and opposite steering-crank 8. The chartbox .embodying my vinvention is indicated by 9, and in this instance of myinvention comprises the rectangular fra-me shown in Figs. l'to 5, which will, presently, be deseribed in detail. The location of the chartis preferably just inside the body of thev car'and upon al bracket 10, supported by the dash-board- 11, at one side of the steeringshaft 4;, afs clearly shown in Figs. l, 2- and 12.

The chart-box may, however,- be secured to .Patented oet. is, 1914.

the front door at the steering-wheel side of the car, the object being' to place the same conveniently for observation and manipulation by the driver. The hub of the wheel, on the steering side of the car, preferably, and on its inside, is provided with a gear 1.2, see Figs. 2 and S, and meshing therewith 1s a pinion 13, carried by the shaft 14, journaled in the gear-box 15, supported upon one of the. arms 6 of the steering-crank, jointed as usual to the shaft 16.. The gearbox 15 has extending therefrom the flexible shaft 19, which is extended to the chart-box at 20, and is'ronnected to the worm-shaftQl, journaled on the bottom of the chart-box in bearings 22, said shaft 21.carrying the worm 23, meshing with the worm-gear 24, carried by the vertical shaft. 25, havingD at its upper end the worm 26, secured in proper position thereon by the collar 27. The shaft 25 is held in vertical position by the standard 28, having the sleeve 29 extended at a rightangle therefrom, through which the shaft 25 passes and which latter is prevented from having vertical movement in its bearingsby the collar 30, secured thereto beneath the sleeve 29. T he lower end of the shaft 25 is also journaled in the base 3l of the standard 28, see Fig. 3. The shaft 21 extends transversely of the chart-frame or box substantially midway between its ends and the shaft 25 extends vertically within the said box substantially midway between its sides. The chart-frame or box consists of the bottom vportion 32, which supports all the elements of my apparatus, and a removable 'cover consisting of the opposite side-portions 33 and 34, the opposite end-portions and 36, and the top-portion including the rectangular frame 37 seated upon the sides and ends and having set therein the plate-glass or other suitable transparent medium 3S, through which to view the operations of the indicating-arm and chart-web. Nithin the box thus constructed, four end-supports are provided, two being at the front end and indicated by 39 and twov being at the rear end and indicated by 40. Midway between the said pairs of supports and on the opposite sides ofthe box are the supports 41. The front supports 39 have journaled therein the receiving web-cylinder 42, provided in its center with the cut-out portion 43, provided with a hook 44, to which one end of the web 45 is secured. The web, in its travel, extends over an idle-roll 46, at one end of the table 47, which extends substantially from end to end of the box and terminates adjacent a similar idleroll 48, journaled in the opposite supports 40. The web, at the opposite end of the table 47, extends over the roll 48 and down to the delivery web-cylinder 49. having a cut-out space and hook the same as the cylinder 42, the cylinder 49 being journaled in the supports 40. The web-cylinder is provided at its opposite ends, outside the supports 39, with the pulleys 50, around which extends the bauds` 51, and each of which runs to a pulley 52, carried at the opposite ends of an angular shaft 53, journaled in the supports 41. Slack take-up rolls 54 are carried by the bars 55, secured to the opposite supports 41, said rolls engaging the lower strand of the respective belts 51. Viewing Figs. 6 and. 7 it will be seen that the pulleys are carried by the elongated journals 56, upon which are set the gears 57 the hub of which extends oppositely to the journal 56, the pulleys and gears thus embracing the respective supports 41. Th e an gul ar shaft 53 is sufficiently long to extend from side to side of the box and into an aperture 58, in one side or the other of said box; and said shaft is longitudinally movable in the journals 56, of the pulleys' 52, said movement being limited in one direction by the collar 59, set upon said shaft and adapted to engage with the adjacent gear 57. In the opposite direction, the shaft 53 is limited in its movementby the coiled-spring 60, surrounding said shaft' and engaging at one end the face of the adjacent gear 57, and at its other end a collar 61, set upon the said shaft. The knob-extension 62 enables manipulation of the shaft longitudinally, and also axially when the worm-gear 63, ixed thereto substantiallyY midway between its ends, is thro-wn out of engagement with the worm `26, carried by the shaft 25, the spring 60.

under this condition, as shown in Fig. 7,

being compressed and having power stored therein capable of forcing the shaft in the opposite direction until the collar 59 engages the adjacent gear 57 and the gear 63 again goes into mesh with the worm 26, as shown in Fig. 6. y

A presser-roll 64 is arranged at each corner of the box, one pair being journaled upon the supports 39 and the other upon the supports 40, these rolls having the function of maintaining the web 45 in depressed position and in proper coperation with the idle-rolls 46 and 48, it being noted, upon reference to Figs. 4, 6 and 7, that the web 45, along its opposite margins, is provided Ywith a series of angular apertures 65, in which,

and with the walls of which, the teeth of the p `gears 57 engage to positivelyA feed the web from one roll to the other in the direction of the arrow, Fig. 4. The pulleys 50 and 52 and the band 51, connecting the same, are for the purpose of aiding the, feed of the web 45 and overcoming any back-drag which might occur by reason of the weight of the web on the cylinder 42. A tensiondevice consisting of the anti-friction roll 66 is maintained in engagement with the web en the cylinder 49, by means of the tensionsprng 67, secured to the base of the'box 32,

by the screw 68. Thus the feed of the web is .imparted from the driving-gear 12-13,

through the iexible shaft 19, horizontal shaft 23, vertcal shaft 25 and angular shaft 53 imparting rotation to the web-feed-gear 57.

The connecting-rod 5 has secured thereto, in any suitable manner, a rod 69, connected to the crank-arm 70, in turn connected to the flexible shaft 71, said shaft, at its upper end, being connected at 72, Figs. l and 5, with the vertical shaft 73, journaled in the bottom 32. at the front end of the box, and near its upper end being journaled inthe bearing 74, secured to one of the supports The bearing T4 has extending vertically therefrom an arm 75, having at its upper end the angular bearing 76, in which slides the bar 77, having at one end a shox-track 78, engaging pinion 79, carried on the upper end of the shaft 73. The other end of the bar 77 is also provided with a. short rack 80, meshing with the pinion 81, carried on the journal of the arm 82, Fig. 3, mounted to swing upon the cone-points 83 bearing in the opposite lugs 84, of an arm 85, carried by the opposite support 39. The arm 85, adjacent the lugs 84, is also provided with the bearing 86, in which slides the adjacent end of the bar 77. In order to take up wear, or secure thev proper adjustment, the lower lug 84 is provided with a screw-bearing 87, for the lower cone-point 83. The forward end of the arm 82 is provided with a holder or socket 88, in which may be secured a pencil or tracingpoint 89, which bears lightly upon the web 45. Thus, control of the arm is maintained through the connection 69, with the fiexible shaft 71, and the steering-shaft 4, and it will be seen that every movement in either direction given to the steering-shaft 4 will be imparted correspondingly to the tracingarm 82, and a corresponding record will be made upon the web 45. In fact, every direction given to the car, according to the manner in which the car is steered, will be accurately charted upon the web 45, as shown in Fig. 4; and every direction indicated on the chart already made canbe followed accurately by the driver of the car by simply manipulating the steering-wheel in such manner as to follow with the tracingpoint the charted lines indicating the direc-4 tion to be followed. This will he readily understood upon reference to Fig. 4.

In the form of my invention shown in Fig. 11, the rack-bar 77 is extended beyond the chart-frame, as at 90, and has jointed therewith the connecting-rod 91, which, at its opposite end, is pivoted at 92, to the hub of the steering-wheel 3, or to the shaft 4, as desired. By this means, the arm 82 is given every movement which is imparted to the steering-wheel and, consequently, the map or chart fed through the apparatus can be accurately followed, or, if a chart is being made, every bend. curve and turn in the road can be accurately charted.

In the form of my invention shown in Fig. 12, the crank 70, of; the flexible shaft 71. is connected by the rod 93, directly to the arm 6 of the steering-crank, this giving a direct connection from the steering-crank to the said flexible shaft instead of transmitting the movement to said shaftby the intermediate connection 69, from the rod 5, or the adjacent portion of the steering mechanism of the car.

In Figs. 9 and 10, I have shown a means by which the web-cylinders I42 or i9 can be released from their supports and, particularly, I have illustrated, for example, the web-cylinder 42, as provided with the hollow spindle 94, journaled at one end upon the extended end 95, of a. pin 96, projecting through the bearing 97, in one of the supports 39 and having at its outer end the manipulating head 98, whereby the pin may be withdrawn to withdraw the end 95 thereo fl from the spindle 94. the pin, the head 99 thereof compresses the spring 100, within the socket 101, with a tendency to return the pin after the release thereof by the cross-bar 102, which has been turned across the end of the bearing 97, after being withdrawn from its slot 103. The opposite end of the spindle 94 may or ,may not be supported in similar manner, as

desired. And it will be readily seen that, by manipulating the head 98 of the pin, a spindle may be set in and removed from the frame easily and at will.

Having thus described the details of my 'inventiony the following mode of operation will be readily understood: Assuming a car to be rigged with my apparatus and the party to be desirous of following a given route represented by the charted lines 105 thereof, on a given web 45, the latter will be set in the frame after its cover, comprising the top, two sides and ends have been removed; that is to say, the web-spindle, at one end, willbe entered in the slot 104, Fig. 5, of one of the supports 39, and the pin 96 will then be withdrawn and held as in Fig. 10. until the spindle 94 is made to register with the `end 95 of said pin. The latter will then be released and the cylinder will be properly supported in the machine. The web on the delivery-cylinder 49 will then be set in place and the end of the web will then be carried vertically around the idleroll 48, Figs. 3 and 5, and under the two adjacent depressing-rolls 64, over the table 47, and between the idle-roll 46 and coperating depressing-rolls 64 at the other end of the frame, then downwardly to the spindle 42, on the hook of which the end of the web will be caught. The tension-roll 66 will bearagainst the web on cylinder 49 and automatically apply its tension as-the latter is In withdrawing i adjusted upon the'pulleys 50 and 52. The

cover will now be set in -place with the shoulder 106 around its bottom edge in place upon the top surface of the bottom 32, of the a'pparatus. In this position, the cover is locked in place pins108 on the bottom 32, thus preventing the cover from rattling or becoming displaced during travel. The apparatus is thus made ready for use for making a chart of the road or following a chart or map already made. The steering-wheel will then be manipulated by the driver so as to bring the point S9 upon the line and atthe point from which the car starts on its journey under the directionsxgiven on the chart. As the car travels. the web will be fed from the delivery-cylinder -19 to the receiving-cylinder 42, by the gears engaging the margins of the web and by the driving-band 51, the latter medium being employed to relieve the web of drag which might be occasioned by the weight of the web,or`friction of the cylinder 42 thereof in its bearings. The driver of the car controls the action of the arm 82 and its point 89, since he controls the direc tion of movement of the car and said arm is directly7 to the speed of the car by the gearing shown, is approximately ten to one; that is to say, for every ten miles of travel of t-he car, the chart-web 45 will move one foot. With the direction of movement ofthe car lforward, as shown, for example, in Fig. 2, the driving-gear l2 will move in the direction of the arrow a., Fig. 8, Vthe pinion 13 in the direction of the arrow 7), and the flexible shaft 19 in the direction of the arrow c. This will cause the worm-shaft 21 to rotate in the direction of the arrow d, Fig. 3, the vertical shaft 25 in the direction of the arrow e, the gearing 57 and 63 in the direction of the arrow f, and the web will be caused to travel in the direction of the arrow g. thus carrying the web fromxthe delivery-cylinder 49 to the receiving-cylinder 42, the band 51 traveling in the direction of the arrow z..

Practically the same procedure will be carried out provided the party in the car is desirous of producing a chart, or charting the route pursued by it. That is to say, a cylinder of appropriate paper will be placed in the machine. a pencil substituted for the tracing-point 89, and the car started into operation. For every movement given the steering mechanism, as in turning curves, corners, bends, etc., a correct delineation by swinging the pivoted latches 107 on the cover, for example, under the headedconnected with the steering mecha-- nism. The feed of the web, with reference' thereof will be traced u on the web 45 and, in addition thereto, w en road-houses or `other indicating monuments are reached, one

or two vibrations of the pencil can' be given to note the fact and place on the chart, which latter can be subsequently gone over and indexed so that, in following the same thereafter,the driver of the car will know the various monuments as they occur inthe road and can vsee whether they tally with'the ones on the chart.

-'Vhile I have described my invention as applied to a road vehicle of the automobile type, I desire. to have it understood that it is equally applicable to vehicles of other types, whether traveling on land, water, or tracks, and that, in my claims, I purpose covering my invention by language broad enough to comprehend all types of vehicles irrespective of how propelled or where traveling.
